Electrical Installation
HAZARD
Dangerous voltage levels may still be present inside the unit and at the terminal strips
up to 10 minutes after the complete axis system has been disconnected from the
mains.
Severe or fatal injuries from electric shock.
To prevent electric shocks:
• Disconnect the axis system from the mains and wait ten minutes before removing
the covers.
• After maintenance work, do not operate the axis system unless you have replaced
the cover because the unit only has degree of protection IP00 without the cover.
HAZARD
A leakage current > 3.5 mA can occur during operation of the MOVIAXIS
®
MX multi-
axis servo inverter.
Severe or fatal injuries from electric shock.
To prevent electric shock:
• With a supply system lead < 10 mm
2
, route a second PE conductor with the same
cross section as the supply system lead via separate terminals. Alternatively, you
can use a PE conductor with a copper cross section
≥
10 mm
2
or aluminum
≥
16 mm
2
.
• With a supply system lead
≥
10 mm
2
, it is sufficient to install a PE conductor with a
copper cross section
≥
10 mm
2
or aluminum
≥
16 mm
2
.
• If an earth leakage circuit breaker can be used for protection against direct and in-
direct contact, it must be universal current sensitive (RCD type B).
NOTE
Installation with reliable isolation.
The unit meets all requirements for reliable isolation between power and electronic
connections according to EN 61800-5-1. The connected signal circuits have to meet
the requirements according to SELV (
